Greedy little buggers! Haha well ok then, good to knowEventually food, Mr Wilson can eat something much larger than you think, and cardinals are sitting ducks. Any fish that is about half their size can be eaten, it could be immediately, or even in a year. I've watched my scorps and lions stalk out sleeping spots to ambush and eat fish way bigger than I thought possible. Here's a pic of one of my S. brasiliensis with the tail of molly sticking out of his mouth, that molly was about 2/3rds his size and meant for the rhino, that little rascal was a beast.
